Ningbo Oulai Building Hardware Co., Ltd. is a building hardware manufacturer. Now I will briefly introduce what building hardware is.

Construction hardware The general term for metal and non-metal products and accessories used in buildings or structures. Generally it has the dual effect of practicality and decoration. Architectural hardware started in hand workshops such as ironsmith shops, coppersmith shops and tinsmith shops. With the widespread use of metal materials and the needs of social life, construction hardware has developed rapidly, and there have been many small factories or workshops that produce steel nails, hinges, latches, window hooks, faucet valves, and wire woven screens. Later, mechanical processing equipment was gradually used to replace manual production, forming many specialized enterprises.
With the continuous improvement of the standards of various building facilities, modern building hardware products have developed from a single variety to a series, and the requirements for their beauty and decorative effects are getting higher and higher. The production technology of construction hardware products has also made great progress. Most products have evolved from semi-manual and semi-mechanical operations to semi-automatic or fully automatic mechanical assembly line production. Building hardware has expanded from traditional copper alloys and low-carbon steels to zinc alloys, aluminum alloys, stainless steel, plastics, fiberglass and various composite materials.
